SunKeeper

Morningstar’s SunKeeper is a three stage PWM charge controller that provides a low cost, regulated
output directly from the solar module to maximize battery life in small solar applications. The
SunKeeper is epoxy encapsulated and rated for outdoor use; designed for solar power systems in the
oil and gas industry. By mounting directly to the module junction box and wiring through the junction
box knockout, the connection is weather-proof and eliminates the need for an additional housing for
the controller. 5-year warranty.

Features include:
• 6 or 12 Amp versions
• Rated to 70°C

• Certified for use in Class 1, Div. 2 hazardous locations
